Hair analysis is now recognized as a robust method for detecting alcohol and drug consumption. Hair captures a prolonged history of these substances by embedding biomarkers within the hair strand fibers as they grow. When obtained near the scalp, hair can offer nearly a three-month window for identifying alcohol and other drug use. It is easy to collect, challenging to tamper with, and convenient to transport.
A 1.5-inch segment of approximately 200 hair strands (comparable to a #2 pencil in size) near the scalp yields around 100mg, the optimal amount for both screening and confirmation. For EtG, additional analyses, and/or assessments exceeding 10 panels, it is advisable to collect 150mg of the sample. Using a jeweler’s scale is suggested for weighing the specimen. When scalp hair is not accessible, an equivalent quantity of body hair can be obtained. By head hair, we mean scalp hair exclusively. Body hair encompasses all other types (such as facial, axillary, etc.).
Process Overview
The laboratory procedure for processing a drug test result consists of four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a sample into the lab's system. This phase involves checking that the sample was properly sealed and delivered, allocating a random LAN (Laboratory Accessioning Number), and completing any extra data input missing from an electronic chain of custody system.
Screening entails a preliminary rapid assessment for substances of abuse. Though Screening is a cost-efficient strategy for eliminating drug use in most samples, a positive screen necessitates confirmation for legal admissibility. Samples with tentative positive results in Screening require subsequent confirmation.
If Screening yields a presumptive positive, additional hair is extracted from the original sample for the Extraction phase. During this stage, substances are separated from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.
Confirmation of any positive screening outcome is executed via GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all tentative positive samples undergo washing as necessary. The entire lab procedure from Accessioning to Confirmation undergoes scrutiny under the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Although often termed as "hair follicle tests", the test inspects the hair strand rather than the follicle under the scalp.

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.
It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.
Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing. Remarkable advancements in sample preparation, detection, and identification of drug compounds have been presented. The manuscripts in this section presented novel approaches, such as multianalyte methods and on-line preparation which can enable rapid analysis and improve thorough forensic investigations.
Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.
Forensic Applications and Interpretation: One of the vital objectives of hair testing is its application in forensic investigations and legal proceedings. The SoHT meeting in Verona emphasized the significance of rigorous interpretation of analytical results and the need for standardized protocols. Manuscripts in this section present advancements in forensic toxicology, and have explored the challenges posed by emerging designer drugs and strategies to combat their proliferation. The pitfalls encountered when the exogenous/endogenous nature of a substance is questioned were presented and discussed. The special issue presents also manuscripts that delve into the ethical implications of drug testing in drug facilitated sexual assaults.
Clinical Applications of hair testing are witnessed by the insight on environmental tobacco smoke exposure, assessed by hair analysis in a population of students and the study of in utero-exposure to drugs of abuse through neonatal hair analysis. Exposure to drugs was also important in cases of child abuse/neglect, when the clinical purpose of hair testing merge with its forensic applications.
The legal framework surrounding hair testing and the achievement of guidelines to ensure fairness, accuracy, and confidentiality in drug testing practices have also been discussed,and the SoHT consensus on general hair testing and testing for drugs of abuse was presented at the meeting and published as a Letter to the Editor.
In conclusion, the special issue of Drug Testing and Analysis, featuring manuscripts from the SoHT–GTFI meeting in Verona 2022, reflects the remarkable advancements achieved in this field. The manuscripts provide valuable insights into novel analytical techniques, biomarkers, pharmacokinetics, forensic applications, and ethical considerations.
